Since a power set itself is a set, we need to use a pair of left and right curly braces (set brackets) to enclose all its elements. Its elements are themselves sets, each of which requires its own pair of left and right curly braces.

Consider the function which gives the number of children of each person reading this. What is the range? I'm guessing it is something like . { 0, 1, 2, 3 }. Maybe 4 is in there too. But certainly there is nobody reading this that has 1.32419 children.

WebExample. Negate the statement "If all rich people are happy, then all poor people are sad."

The key thing to remember is: If x ∈ f − 1(D), then x ∈ A, and f(x) ∈ D. It is possible that f − 1(D) = ∅ for some subset D. If this happens, f is not onto. Therefore, f is onto if and only if f − 1({b}) ≠ ∅ for every b ∈ B.
